+Device-Tree bindings for generic vga encoders
+
+Required properties;
+ - compatible: must be "adi,adv7123"
+
+Optional properties:
+ - ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
+ - enable-gpio: GPIO pin to enable or disable the encoder
+ - vaa-supply: regulator for the analog power supply
+
+Example:
+
+ adv7123: vga-encoder {
+ compatible = "adi,adv7123";
+ ddc-i2c-bus = <&i2c4>;
+ vaa-supply = <&vcc_io>;
+ enable-gpio = <&gpio0 17 GPIO_ACTIVE_HIGH>;
+ };
